Weighted hula hoops can be purchased from most sporting goods stores and large retailers or their websites. Dick's Sporting Goods and Amazon are just two examples. Others include Walmart, Target and Sports Hoop.
While all of these establishments advertise weighted hula hoops, the ability to purchase one may vary by location. Prior to visiting the store, it is best to call. A sporting goods or fitness store typically keeps more in stock than a retail store. Also, a sporting goods or fitness store often offers a wider selection of weight increments than the large retailers. For example, Dick's Sporting Goods sells a Stamina 2.5 pound fitness hoop and more customizable options.
